The twin sisters, Twist (left) and Speedy (right) are sisters who work as waiters on skates. They love fruit, and 'accidently' triping and eating others. Twist is the older of the 2, but isn't as tough as Speedy.
Well think like this, Speedys skaiting with an ourder of hot soap in hand, someone accedintly trips her while there walking , she drops the soap and its scalding hot and lands on some poor dudes face. Thats how.
It's a joke on the Memetic Demyx line "Dance water, DANCE!". I used it because the way you created the picture made it look like Twist and Speedy are dancing from how I interpreted it. Please find my overused joke funny.
